I don't understand why I keep getting it wrong. Please help.
Let's wrap it all up!
On line 3, create the variable my_string and set it to any string you'd like.
On line 4, print the length of my_string.
On line 5, print the .upper() case version of my_string.
4 print str(4)
5 print power.upper()
It keeps saying "Oops, try again. Did you create a variable called my_string?"
If anyone can help me that would be great thanks.
